Test tc cursor mouse operation (TC)

Test tc cursor mouse operation (TC)
The mouse operation code used in the Code is controlled by the common registers _ AX, _ BX, _ CX, _ DX.
I really want to use TC multithreading to solve this problem, but I didn't find a specific implementation method on the Internet. Is there only a multi-thread method in C ++ or MS VC? Annoying

int main(){    char szText[20] = "";    for(;;)    {        if(LeftPress())        {            MouseGetXY();            if(MouseX < 0 || MouseX > 800 || MouseY < 0 || MouseY > 600)                printf("Cursor is not in the Active Area of the screen!\n");            else            {                printf("LeftButton Pressed!\n");                sprintf(szText, "cursorX,Y:(%d, %d)\n", MouseX, MouseY);                printf(szText);            }            //sleep(1);        }        if(RightPress())        {            MouseGetXY();            if(MouseX < 0 || MouseX > 400 || MouseY < 0 || MouseY > 300)                printf("Cursor is not in the Active Area of the screen!\n");            else            {                printf("RightButton Pressed!\n");                sprintf(szText, "CursorX,Y:(%d, %d)\n", MouseX, MouseY);                printf(szText);                /*moveto(120,240);*/                textcolor(5);                cprintf("/*RButton Test*/");                printf("\n");            }            //sleep(1);        }        if(kbhit())        {            if(0x011b == bioskey(0))            {                printf("\ntestEnd\n");                break;            }        }        if(!LeftPress() && !RightPress())            continue;        printf("test again:\n");    }    getch();}

Problem: When the code is left-pressed or right-clicked, the print statement is printed multiple times.

Solution: After all the corresponding statements are executed, add a sleep (1.

Cause: this problem should be caused by multi-thread round robin;
Textcolor (6 );
Textbackground (7 );
Cprintf ("Left and Right button both Pressed! \ N ");
The execution efficiency of these three statements is too low.
